The concentrate is also thickened, and is then reground in a conventional ball mill, prior to CIL, before stripping, electro winning and refining to doré. The regrind ball mill, operates in closed circuit with 25 mm diameter balls and very high recirculation loads ( 600 %), to produce a product with a P80 of 20 m.

It was also realized that regrind mills of ~ 3 5 MW (ball mill equivalent) capacity could be used for both mainstream and concentrate regrind applications in these plants without having to use multiples of small units. The opportunity to demonstrate and develop an M 10 000 IsaMill fitted the WLTR project objectives. It was a relatively

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

Mill Process Grinding Mills. Grinding Mills also know as SemiAutogenous (SAG), Ball or Regrind Mills are used in the primary or early stages of pulverizing the ore in the process plant. This initial grind of the ore is typically completed in two or three stages. The mills are driven by large high horsepower electrical motors and the outer ...

How it works. Eight consecutive grinding chambers, patented product separator and short residence times means the mill constantly delivers sharp product size distribution without external classification. The IsaMill™ is a closed mill. Slurry travels through the mill in a 'plug' flow pattern through consecutive grinding discs.

The large scale of the IsaMill™ makes that efficiency available to mainstream grinding. The high energy efficiency of stirred mills compared to ball mills is well understood. The use of tower mills as an energy efficient alternative to secondary and regrind ball milling became a common inclusion in the latter part of the previous century.

The gravityinduced mills, Tower Mills and Vertimills, are more efficient in the particle size range typical of regrind circuits, down to P 80 values of around 2040 μm, and below this limit fluidised mills are more efficient [22]. This is primarily due to the differences in grinding media size [28], since gravityinduced mills require media ...
